I'm Oussama, an AI Engineer interested in building reliable, efficient, and production-ready AI systems.
I enjoy working across the full AI stack, from data and model fine-tuning to agentic systems, backend infrastructure, deployment, and system optimization. Alongside AI engineering, I'm also exploring AI Security, with a focus on testing, evaluating, and protecting AI systems in production.
